Farnesylation inhibitor
WebProtein farnesylation is a lipid posttranslational modification required for the cancer-causing activity of proteins such as the GTPase Ras. Although farnesyltransferase inhibitors (FTIs) are in clinical trials, their mechanism of action and the role of protein farnesylation in normal physiology are ill understood. In this issue of Cancer Cell, two articles shed light … WebMay 9, 2010 · Farnesyltransferase inhibitors (FTI) are small molecules that inhibit prenylation of multiple proteins, including Ras, RhoB, lamin A/C, and the centromere proteins (CENP-E and CENP-F; refs. 1, 7, 8). Tipifarnib is a FTI that blocks farnesylation by competitively binding to the CAAX motif in proteins .

WebMar 7, 2011 · Protein farnesylation is a posttranslational modification that facilitates the binding of proteins to membrane surfaces. Protein farnesyltransferase catalyzes the addition of a 15-carbon farnesyl lipid to proteins containing a carboxyl-terminal CaaX motif consisting of a cysteine (C) followed by two aliphatic amino acids (aa) and a terminal amino acid …
WebPreclinical evaluation of farnesylation inhibitors will determine the specificity and therapeutic potential. To fill this lacuna, a bioluminescence-based imaging reporter was developed and its suitability was tested using a xenograft of a mouse bearing mammary fat pad or bone-localized breast tumor cells [73] . WebInhibition of the enzyme HMG-CoA reductase results in decreased farnesylation and geranylgeranylation of several proteins essential for cellular proliferation and survival. Inhibition of Ras farnesylation was originally thought to be the mechanism that mediates statin-induced effects in cancer. Consequently, specific inhibitors of the enzyme ...
WebBiological Activity. Potent farnesyl transferase inhibitor (IC50 = 1.9 nM). Inhibits farnesylation of RAS. Also inhibits Pgp transport (IC50 < 3 μM) and increases potency and anticancer activity when used in conjunction with cytotoxic Pgp substrates. Inhibits neovascularization by affecting cell motility. Orally bioavailable.

LNK-754 inhibits the activity of a protein called farnesyl-transferase (FT). This class of molecules are called FTIs (or farnesyl-transferase inhibitors). As with mTOR inhibitors, many companies developed them to treat cancers, where they were unsuccessful. The mechanism by which FTIs work is through inhibition of this enzyme, which adds a fatty acid molecule to proteins (such as the oncoge…
